What is the biggest spacer anyone has ran and did not have to change the studs out?

 

i would say 5mm would be the max, but even then thats already pushing it.

 

thanks, appreciate it.

 

agree with 5mm.

 

5mm is the biggest I would go.

There are spacers with studs built in but I don't know how safe they are. I'd imagine anything under 20mm should be alright with this type of spacer.

 

I've installed 10mm spacers for the front without replacing the studs. For proper and easy alignment, I glued the spacer to the back of the wheel, and I used new lug nuts with longer shaft. Just make sure the spacers you get have large enough holes for the lug nut shaft diameter.

 

i was thinking 10mm might work, i do have aftermarket lug nuts that is longer than oem. i will give it a try to see how tight it is before replacing the studs. Thanks for the help.

 

To be safe, I’d do a dry-fit with the spacer stacked against the wheel, and insert a lug nut to see how far in it gets. Ideally, the lug nut should reach within ¼” to the surface (see picture). The stock studs are about 1” long and you’d want to get about ¾” of it into the lug nut.

 

I ran 15mm front and 25mm rear with out issues for 2 years. These were the ones with studs as someone mentioned.

 

I think OP is asking only about spacers without attached studs.
I was a believer with spacers for years. Always had project Kics spacers until one failed on me with a stud breaking off.

I pretty much wont be using spacers anymore.
